This article deals with medicine as practiced by trained professionals from ancient times to the present.
Early medial traditions include those of ancient
Egypt and
Babylon.
The Greeks went even further, introducing the concepts of medical diagnosis, prognosis, and advanced medical ethics.
The Hippocratic Oath, still taken (although significantly changed from the original) by doctors up to today, was written in
Greece in the
5th century BCE. In the medieval era, surgical practices inherited from the ancient masters were improved and then systematized in Rogerius's
The Practice of
Surgery. Universities began systematic training of physicians around the years 1220 in
Italy. During the
Renaissance, understanding of anatomy improved, and the microscope was invented. The germ theory of disease in the
19th century led to cures for many infectious diseases.
Military doctors advanced the methods of trauma treatment and surgery.
Public health measures were developed especially in the 19th century as the rapid growth of cities required systematic sanitary measures. Advanced research centers opened in the early
20th century, often connected with major hospitals. The mid-20th century was characterized by new biological treatments, such as antibiotics. These advancements, along with developments in chemistry, genetics, and lab technology (such as the x-ray) led to modern medicine.
Medicine was heavily professionalized in the 20th century, and new careers opened to women as nurses (from the
1870s) and as physicians (especially after
1970). The
21st century is characterized by highly advanced research involving numerous fields of science.
The World Health Organization was founded in 1948 as a
United Nations agency to improve global health. In most of the world, life expectancy has improved since then, and was about 67 years as of
2010, and well above 80 years in some countries.
Eradication of infectious diseases is an international effort, and several new vaccines have been developed during the post-war years, against infections such as measles, mumps, several strains of influenza and human papilloma virus. The long-known vaccine against
Smallpox finally eradicated the disease in the
1970s, and Rinderpest was wiped out in
2011.
Eradication of polio is underway.
Tissue culture is important for development of vaccines. Though the early success of antiviral vaccines and antibacterial drugs, antiviral drugs were not introduced until the 1970s. Through the WHO, the international community has developed a response protocol against epidemics, displayed during the
SARS epidemic in
2003, the
Influenza A virus subtype H5N1 from 2004, the
Ebola virus epidemic in
West Africa and onwards.
As infectious diseases have become less lethal, and the most common causes of death in developed countries are now tumors and cardiovascular diseases, these conditions have received increased attention in medical research.
Tobacco smoking as a cause of lung cancer was first researched in the
1920s, but was not widely supported by publications until the
1950s.
Cancer treatment has been developed with radiotherapy, chemotherapy and surgical oncology.
Oral rehydration therapy has been extensively used since the 1970s to treat cholera and other diarrhea-inducing infections.
Hormonal contraception was introduced in the 1950s, and was associated with the sexual revolution, with normalization of abortion and homosexuality in many countries.
Family planning has promoted a demographic transition in most of the world. With threatening sexually transmitted infections, not least
HIV, use of barrier contraception has become imperative. The struggle against HIV has improved antiretroviral treatments, and in the late
2000s (decade), male circumcision was cited to diminish infection risk (see circumcision and HIV). In
2013, the first patient was cured from HIV.[134]
X-ray imaging was the first kind of medical imaging, and later ultrasonic imaging,
CT scanning,
MR scanning and other imaging methods became available.
Genetics have advanced with the discovery of the
DNA molecule, genetic mapping and gene therapy.
Stem cell research took off in the 2000s (decade), with stem cell therapy as a promising method.
Evidence-based medicine is a modern concept, not introduced to literature until the
1990s.
Prosthetics have improved. In
1958,
Arne Larsson in
Sweden became the first patient to depend on an artificial cardiac pacemaker. He died in
2001 at age 86, having outlived its inventor, the surgeon, and 26 pacemakers.
Lightweight materials as well as neural prosthetics emerged in the end of the 20th century.
